    • BRIEF DESCRIPTION OF THE DRAWINGS
  • A better understanding of the present invention will be had upon reference to the following description in conjunction with the accompanying drawings.
  • FIG. 1 is a plan view of one embodiment of a steering wheel and associated display screen of the present invention.
  • FIG. 2 is a flow chart of one embodiment of a vehicle driver interface control method of the present invention.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • FIG. 1 illustrates one embodiment of a vehicle driver interface 10 of the present invention, including a steering wheel 12, a display screen 14, and an electronic processor 16. Steering wheel 12 includes capacitive touch sensors in the form of capacitive touchpad switches 18 a-b near the circumference of steering wheel 12. Processor 16 is communicatively coupled to switches 18 a-b and to display screen 14.
  • Switch 18 b may be disposed on steering wheel 12 at a substantially same vertical level as switch 18 a when steering wheel 12 is in a position to steer the vehicle in a straight ahead direction. In the embodiment shown, switches 18 a-b are substantially rectangular in shape. However, it is to be understood that switches 18 a-b can be of a variety of geometric shapes.
  • Switches 18 a-b may be sized and positioned such that the driver can easily touch switches 18 a-b with his thumbs while keeping his other fingers wrapped around the circumference of steering wheel 12. In one embodiment, switch 18 a is located between eight o'clock and ten o'clock, and switch 18 b is located between two o'clock and four o'clock on steering wheel 12. That is, switch 18 a is located between 60 degrees and 120 degrees in a counterclockwise direction from the top of steering wheel 12, and switch 18 b is located between 60 degrees and 120 degrees in a clockwise direction from the top of steering wheel 12. In other words, each capacitive touchpad switch 18 a-b is disposed between 0 degrees and 30 degrees from an imaginary horizontal line bisecting the steering wheel when the steering wheel is steering the vehicle in a straight ahead direction. Thus, the driver may keep his hands at the recommended 9 o'clock and 3 o'clock positions on steering wheel 12 while putting his thumbs on switches 18 a-b.
  • Switches 18 a-b may extend no more than three inches in a radially inward direction from the outer circumference of steering wheel 12. Thus, a driver with normally sized hands may easily touch switches 18 a-b with his thumbs while keeping his other fingers wrapped around the circumference of steering wheel 12.
  • In one embodiment, switches 18 a-b enable the user to zoom in or zoom out on the image being displayed on display screen 14. For example, the driver may drag one or both of this thumbs in radially outward directions indicated by arrows 20 a-b in order to zoom in, or enlarge, the image being presented on display screen 14. Conversely, the driver may drag one or both of this thumbs in radially inward directions indicated by arrows 22 a-b in order to zoom out, or shrink, the image being presented on display screen 14. Directions 20 a-b are substantially horizontal, radially outward directions, and directions 22 a-b are substantially horizontal, radially inward directions.
  • Switches 18 a-b are described herein as being capacitive touchpad switches. However, it is within the scope of the invention for switches 18 a-b to be other types of switches, such as rocker switches, resistive touchpads, or dials that the driver may use to zoom in or out on the image being displayed. Any of these alternative types of switches may be operated by the user's thumbs while he keeps his other fingers wrapped around the circumference of the steering wheel.
  • Although the invention has been described above as detecting the swiping motion of the user's thumb in only two opposite directions, the human-machine interface (HMI) can detect any gesture as long as it is performed by the driver's thumb while his hands are on the wheel. For example, circular motion by at least one of the thumbs may be detected. However, a straight swipe of the thumb may be better from an ergonomics point of view, and may be more intuitive to the driver.
  • FIG. 2 illustrates one embodiment of a vehicle driver interface control method 200 of the present invention. In a first step 202, a display screen is provided in a motor vehicle. For example, display screen 14 may be provided in vehicle driver interface 10.
  • Next, in step 204, a steering wheel is provided including a capacitive touch sensor positioned and sized to be touched by a driver's thumb while the remaining fingers on the driver's hand are wrapped around an outer edge of the steering wheel. For example, steering wheel 12 includes capacitive touch sensors in the form of capacitive touchpad switches 18 a-b near the circumference of steering wheel 12.
  • In a next step 206, the driver's thumb being dragged in a first direction across the capacitive touch sensor is detected. For example, capacitive touchpad switch 18 a may detect the driver's thumb being dragged across capacitive touchpad switch 18 a in direction 20 a.
  • In step 208, an image presented on the display screen is zoomed in on in response to the driver's thumb being dragged in a first direction across the capacitive touch sensor. That is, in response to detecting the driver's thumb being dragged across capacitive touchpad switch 18 a in direction 20 a, processor 16 may enlarge the image being presented on display screen 14.
  • Next, in step 210, the driver's thumb being dragged in a second direction across the capacitive touch sensor is detected, wherein the second direction is substantially opposite to the first direction. For example, capacitive touchpad switch 18 a may detect the driver's thumb being dragged across capacitive touchpad switch 18 a in direction 22 a.
  • In a final step 212, an image presented on the display screen is zoomed out on in response to the driver's thumb being dragged in the second direction across the capacitive touch sensor. That is, in response to detecting the driver's thumb being dragged across capacitive touchpad switch 18 a in direction 22 a, processor 16 may reduce the image being presented on display screen 14.
  • The foregoing description may refer to “motor vehicle”, “automobile”, “automotive”, or similar expressions. It is to be understood that these terms are not intended to limit the invention to any particular type of transportation vehicle. Rather, the invention may be applied to any type of transportation vehicle whether traveling by air, water, or ground, such as airplanes, boats, etc.
  • The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom for modifications can be made by those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention.
